Abstract : This study addresses a stochastic multi-product lot-sizing (re)manufacturing problem in construction enterprise employing a closed-loop supply chain strategy. The finished products required at the construction sites are provided by production resource using virgin material and remanufacturing resource using recyclable material. Uncertain return and demand lead to unequal information on each CLSC links. The mismatch of demand and supply result in high inventory cost which directly affect the difficulty of establishing anoptimallot-sizing production schedule. For this NP-hard problem, we proposed a nonlinear model formula that is approximated by sample average approximation (SAA) method to transform into a deterministic problem. The experiments demonstrated the proposed method can generate the optimal configuration,thereby reducing the total cost. Keywords - Construction waste recycling，Stochastic programming, Multi-product multi-period lot-sizing schedule optimization，Closed-loop supply chain，SAA，Uncertainty.
